## Resolving Fault 1009 on ABB ACS355 Drive Fault code 1009 (PAR PCU 1) on the ABB ACS355 drive signals an incorrect setting for the motor's nominal speed or frequency. This issue arises when the entered parameters don't align with the motor's specifications or the drive's operational limits. The sources offer guidance on interpreting this fault code and suggest steps for rectification. **Troubleshooting Fault 1009** * **Motor Type Matters:** The first step is to confirm the type of motor connected to the drive: induction motor or permanent magnet synchronous motor. Different calculations apply to each type when verifying parameter settings. * **Induction Motor Checks:** If you are using an induction motor: * **Speed/Frequency Ratio:** Ensure the ratio between the motor's nominal frequency (parameter 9907) and nominal speed (parameter 9908) falls within the acceptable range: 1 < (60 * 9907 / 9908) < 16. * **Speed and Pole Pairs:** Verify that the ratio of the motor's nominal speed to the calculated synchronous speed (derived from nominal frequency and pole pairs) is within the range of 0.8 to 0.992. * **Permanent Magnet Synchronous Motor Checks:** If you're using a permanent magnet synchronous motor: * **Synchronous Speed:** Confirm that the motor's nominal speed perfectly matches the calculated synchronous speed (calculated from nominal frequency and pole pairs). **Additional Verification Steps** Beyond the motor-specific checks, scrutinize these parameters for potential inconsistencies that could contribute to Fault 1009: * **Minimum and Maximum Speed:** Confirm that the minimum speed (parameter 2001) is strictly less than the maximum speed (parameter 2002). * **Minimum and Maximum Frequency:** Likewise, ensure that the minimum frequency (parameter 2007) is less than the maximum frequency (parameter 2008). * **Ratio Limits:** Double-check that the ratios of minimum speed to nominal speed, maximum speed to nominal speed, minimum frequency to nominal frequency, and maximum frequency to nominal frequency all stay within the permissible ranges. **Corrective Actions** * **Parameter Adjustment:** Based on your motor type and the checks above, modify the relevant parameters - motor nominal speed (9908), motor nominal frequency (9907), minimum and maximum speeds (2001, 2002), and minimum and maximum frequencies (2007, 2008) to establish consistency and compliance with the drive's operational limits. * **ID Run:** Especially if you're using vector control with an induction motor, performing an ID run can help the drive automatically determine optimal motor characteristics and potentially resolve parameter conflicts.

Thank you for the info! I actually resolved the first issue. All is well with potentiometer. The new issue, however, is start/stop terminals are wired correctly as the manual states, but when you engage( musthold button in) either start or stop, it changes the rotation, rather than call for start or run. I've been in the eletrical field for 6 years now, but have within the last 2 years dove into controls & automation. I appreciate any info you may be willing the share!

When I engage the start button, the drive says fault 1009. How do i fix this?
## Resolving Fault 1009 on ABB ACS355 Drive
Fault code 1009 (PAR PCU 1) on the ABB ACS355 drive signals an incorrect setting for the motor's nominal speed or frequency. This issue arises when the entered parameters don't align with the motor's specifications or the drive's operational limits. The sources offer guidance on interpreting this fault code and suggest steps for rectification.
**Troubleshooting Fault 1009**
* **Motor Type Matters:** The first step is to confirm the type of motor connected to the drive: induction motor or permanent magnet synchronous motor. Different calculations apply to each type when verifying parameter settings.
* **Induction Motor Checks:** If you are using an induction motor:
* **Speed/Frequency Ratio:** Ensure the ratio between the motor's nominal frequency (parameter 9907) and nominal speed (parameter 9908) falls within the acceptable range: 1 < (60 * 9907 / 9908) < 16.
* **Speed and Pole Pairs:** Verify that the ratio of the motor's nominal speed to the calculated synchronous speed (derived from nominal frequency and pole pairs) is within the range of 0.8 to 0.992.
* **Permanent Magnet Synchronous Motor Checks:** If you're using a permanent magnet synchronous motor:
* **Synchronous Speed:** Confirm that the motor's nominal speed perfectly matches the calculated synchronous speed (calculated from nominal frequency and pole pairs).
**Additional Verification Steps**
Beyond the motor-specific checks, scrutinize these parameters for potential inconsistencies that could contribute to Fault 1009:
* **Minimum and Maximum Speed:** Confirm that the minimum speed (parameter 2001) is strictly less than the maximum speed (parameter 2002).
* **Minimum and Maximum Frequency:** Likewise, ensure that the minimum frequency (parameter 2007) is less than the maximum frequency (parameter 2008).
* **Ratio Limits:** Double-check that the ratios of minimum speed to nominal speed, maximum speed to nominal speed, minimum frequency to nominal frequency, and maximum frequency to nominal frequency all stay within the permissible ranges.
**Corrective Actions**
* **Parameter Adjustment:** Based on your motor type and the checks above, modify the relevant parameters - motor nominal speed (9908), motor nominal frequency (9907), minimum and maximum speeds (2001, 2002), and minimum and maximum frequencies (2007, 2008) to establish consistency and compliance with the drive's operational limits.

my drive will only run if I HOLD the start button, what am I doing wrong? wired the same way
Did you fix the problem is so how cause i have the same problem
Explain dcs 500 programming and internal circuits diagram
